Overview

Randomized trial compares airway dimensions post-surgery in OSA patients versus controls, highlighting airway improvements.

Key Points

  • The aim is to evaluate whether maxillomandibular advancement surgery normalizes upper airway dimensions in adults with obstructive sleep apnea.
  • Included 19 controls and OSA patients (n=19, n=12 for conventional MMA, n=7 for modified MMA) in the analysis.
  • Used presurgical and postsurgical cone-beam computed tomography scans to measure airway dimensions.
  • Investigated changes in airway length, volumes, and cross-sectional areas before and after surgery.
  • Both surgical groups demonstrated significant reduction in airway length and increased nasopharyngeal volume (P<0.05).
  • Total airway volume and mean cross-sectional area increased significantly in the conventional MMA group (all P<0.05).
  • Minimal retropalatal and retroglossal cross-sectional areas remained significantly smaller in both surgical groups compared to controls (all P<0.001).
